バリ取り装置によるバリ取り処理時には、バリ取り部材により削り取られたバリの粉塵や、摩耗により生じるバリ取り部材の粉塵が発生する。これらの粉塵がワークに付着している油と混じり合ってヘドロ状となり、図14のように、ヘドロ状の異物60が、搬送ベルト4の搬送面4aに付着したり、透孔4bに溜まったりする。搬送コンベア4はゴム等の柔軟性のある材料で作られているため、使用中のバリ取り部材との接触による摩耗で、透孔4bの搬送面4a側の部分が搬送面4aに対して凹んだ凹み部4baとなっており、この凹み部4baに異物60が溜まり易い。このようなヘドロ状の異物60は、後で加工するワークに対して悪影響を与える。特に、透孔4bに残されたヘドロ状の異物60は、ワークの裏面に付着して吸引痕として残る。   At the time of the deburring process by the deburring device, deburring dust scraped by the deburring member and deburring member dust caused by wear are generated. These dusts mix with the oil adhering to the workpiece and become sludge-like, and as shown in FIG. 14, sludge-like foreign matter 60 adheres to the conveyance surface 4a of the conveyance belt 4 or accumulates in the through holes 4b. To do. Since the transport conveyor 4 is made of a flexible material such as rubber, a portion of the through hole 4b on the side of the transport surface 4a is recessed with respect to the transport surface 4a due to wear due to contact with the deburring member in use. It becomes the dent part 4ba, and the foreign material 60 tends to accumulate in this dent part 4ba. Such sludge-like foreign matter 60 adversely affects a workpiece to be processed later. In particular, the sludge-like foreign matter 60 left in the through hole 4b adheres to the back surface of the workpiece and remains as a suction mark.

この発明の目的は、ワークを搬送する搬送ベルトの搬送面やワーク吸着用の透孔に粉塵や油等の異物が残ることを防ぎ、次のワークに悪影響を与えないバリ取り装置を提供することである。
この発明の他の目的は、上記目的のために設けられる排気吹付け手段を効果的な位置に配置することである。
この発明のさらに他の目的は、搬送ベルトの搬送面に付着した異物を除去する効果を高めることである。
この発明のさらに他の目的は、搬送ベルトの各透孔に均等に排気を吹き込んで、各透孔に溜まった異物を効果的に排出させることである。
An object of the present invention is to provide a deburring device that prevents foreign matters such as dust and oil from remaining on a conveying surface of a conveying belt that conveys a workpiece and a through hole for adsorbing a workpiece, and that does not adversely affect the next workpiece. It is.
Another object of the present invention is to arrange exhaust blowing means provided for the above purpose at an effective position.
Still another object of the present invention is to enhance the effect of removing foreign substances adhering to the conveying surface of the conveying belt.
Still another object of the present invention is to blow the exhaust air uniformly into each through hole of the transport belt and to effectively discharge the foreign matter accumulated in each through hole.

この発明のバリ取り装置は、搬送面からその裏面に貫通する無数の透孔が形成された無端の搬送ベルトを有し、この搬送ベルトの前記搬送面の上に、バリが上面に形成されたワークを載せて搬送するベルトコンベアと、このベルトコンベアの上方に配置されて前記搬送ベルト上のワークのバリを取るバリ取りヘッドと、前記搬送ベルトの裏面側から前記透孔を通じてエアを吸引し、ワークを前記搬送面に吸着させるエア吸引手段と、前記エア吸引手段のエア吸引用ブロアの排気の一部を前記搬送ベルトの前記搬送面に吹き付ける排気吹付け手段とを備える。   The deburring device of the present invention has an endless transport belt in which an infinite number of through holes penetrating from the transport surface to the back surface thereof is formed, and a burr is formed on the upper surface of the transport surface of the transport belt. A belt conveyor that carries and transports a workpiece; a deburring head that is disposed above the belt conveyor to deburr the workpiece on the conveyor belt; and sucks air through the through holes from the back side of the conveyor belt; Air suction means for adsorbing the workpiece onto the transport surface; and exhaust spray means for spraying a part of the exhaust air of the air suction blower of the air suction means onto the transport surface of the transport belt.

この構成によると、エア吸引手段により搬送ベルト上のワークが搬送ベルトの搬送面に吸着された状態で、ベルトコンベアによってワークが一定方向に搬送される。搬送中に、ワークがバリ取りヘッドの下方を通過し、バリ取りヘッドによってワークの上面に形成されているバリが取られる。   According to this configuration, the work is conveyed in a fixed direction by the belt conveyor in a state where the work on the conveyance belt is attracted to the conveyance surface of the conveyance belt by the air suction unit. During the conveyance, the work passes below the deburring head, and the deburring formed on the upper surface of the work is removed by the deburring head.

バリ取りヘッドによるバリ取りの際に生じるバリの粉塵やバリ取りヘッドのバリ取り部材の粉塵と、ワークに付着している油とからなる異物が、搬送ベルトの搬送面に付着したり、搬送ベルトの透孔に溜まったりする。しかし、排気吹付け手段により、エア吸引手段のエア吸引用ブロアの排気の一部を搬送ベルトの搬送面に吹き付けることで、搬送ベルトの搬送面に付着した異物および搬送ベルトの透孔に溜まった異物を除去、または除去され易くする。具体的には、風圧で異物を飛ばして除去する。あるいは、風で異物や搬送ベルトの搬送面を乾燥させて、搬送面が下向きになったときに、異物が搬送ベルトから剥離して自重で落下し易くする。   Debris generated during deburring by the deburring head, debris from the deburring member of the deburring head, and foreign matter consisting of oil adhering to the workpiece adhere to the conveying surface of the conveying belt, or the conveying belt Or accumulated in the through hole. However, a part of the exhaust of the air suction blower of the air suction means is blown to the transport surface of the transport belt by the exhaust spraying means, and accumulated in the foreign matter adhering to the transport surface of the transport belt and the through hole of the transport belt. Foreign matter is removed or easily removed. Specifically, the foreign matter is blown away by the wind pressure and removed. Alternatively, the foreign matter and the conveying surface of the conveying belt are dried with wind, and when the conveying surface is directed downward, the foreign matter is peeled off from the conveying belt and easily falls by its own weight.

この発明において、前記排気吹付け手段は、前記搬送ベルトにおける戻り部分の搬送面に、前記エア吸引用ブロアの排気の一部を吹き付けると良い。搬送ベルトにおける戻り部分は、搬送ベルトの移動経路中のワークの搬送を行わない部分のことである。
搬送ベルトにおける戻り部分の搬送面は、ワークが吸着された状態となることがないので、戻り部分の搬送面に排気を吹き付ければ、搬送ベルトの搬送面に付着した異物および搬送ベルトの透孔に溜まった異物を除去、または除去され易くする効果が高い。
In this invention, it is preferable that the exhaust spray means sprays a part of the exhaust air from the air suction blower onto the transport surface of the return portion of the transport belt. The return portion of the transport belt is a portion where the work is not transported in the travel path of the transport belt.
The transport surface of the return portion of the transport belt does not become a state where the workpiece is adsorbed, so if exhaust is blown to the transport surface of the return portion, foreign matter adhering to the transport surface of the transport belt and the through hole of the transport belt It is highly effective to remove or easily remove foreign substances accumulated in the water.

この発明において、前記搬送ベルトの前記搬送面における、前記排気吹付け手段により前記エア吸引用ブロアの排気の一部を吹き付ける箇所よりも搬送ベルト移動方向の上流側に、前記搬送面に付着した異物を掻き取る掻き取り手段を設けても良い。
上記位置に掻き取り手段を設けると、搬送面に大量の異物が付着している場合でも、排気吹付け手段で排気を吹き付ける前に異物の大半を除去しておくことができる。そのため、排気を吹き付ける効果が残された異物の深層部まで行き渡り、異物が綺麗に除去され易い。
In this invention, the foreign matter adhering to the conveying surface on the conveying surface of the conveying belt is more upstream in the moving direction of the conveying belt than a portion where a part of the exhaust of the air suction blower is blown by the exhaust blowing means. You may provide the scraping means which scrapes off.
When the scraping means is provided at the above position, even when a large amount of foreign matter adheres to the transport surface, most of the foreign matter can be removed before the exhaust is blown by the exhaust blowing means. Therefore, it reaches the deep part of the foreign matter where the effect of blowing exhaust gas remains, and the foreign matter is easily removed cleanly.

この発明において、前記搬送ベルトの前記透孔は、搬送ベルトの移動方向および幅方向に対して散在状態で配置され、かつ前記排気吹出し手段における前記エア吸引用ブロアの排気の一部を吹き出す吹出し口は、前記搬送ベルトの幅方向に長いスリット状であっても良い。
搬送ベルトの透孔が搬送ベルトの移動方向および幅方向に対して散在状態で配置されていても、排気吹出し手段の排気の吹出し口が搬送ベルトの幅方向に長いスリット状であれば、すべての透孔に均等に排気を吹き込むことができる。

この発明の一実施形態を図1ないし図12と共に説明する。このバリ取り装置は、図1および図2に示すように略直方体の外部カバー40を有し、この外部カバー40の内部に、図3ないし図5に示すように、ワークWを載せて搬送するベルトコンベア1と、このベルトコンベア1の上方に位置し搬送方向(矢印X方向)に並べて配置された第1および第2のバリ取りヘッド11,12とが設けられている。ワークWは、板金等の平板状の板材であって、孔hの孔明け加工や切断加工等が、パンチプレスやその他の板材加工機により施されたものである。   An embodiment of the present invention will be described with reference to FIGS. This deburring apparatus has a substantially rectangular parallelepiped outer cover 40 as shown in FIGS. 1 and 2, and a work W is placed inside the outer cover 40 and conveyed as shown in FIGS. 3 to 5. There are provided a belt conveyor 1 and first and second deburring heads 11 and 12 arranged above the belt conveyor 1 and arranged side by side in the conveying direction (arrow X direction). The workpiece W is a flat plate material such as a sheet metal, and the hole h is punched or cut by a punch press or other plate material processing machine.

ベルトコンベア1は、コンベアフレーム2の前後両端にそれぞれ設けられた一対のローラ3に、無段の搬送ベルト4を掛装して構成される。搬送コンベア4は、ゴム等の柔軟性のある材料で作られている。搬送方向下流側のローラ3は、モータ等の駆動源5により駆動される。コンベアフレーム2は、直方体形状の本体フレーム13に設置されている。   The belt conveyor 1 is configured by a stepless conveyance belt 4 being hung on a pair of rollers 3 provided at both front and rear ends of a conveyor frame 2. The conveyor 4 is made of a flexible material such as rubber. The roller 3 on the downstream side in the transport direction is driven by a drive source 5 such as a motor. The conveyor frame 2 is installed on a main body frame 13 having a rectangular parallelepiped shape.

ベルトコンベア1には、ワークWを搬送ベルト4の搬送面4aに吸着させるエア吸引手段6が設けられている。このエア吸引手段6は、図11に示すように、搬送ベルト4の全面に分散して無数に設けられ搬送面4aから裏面へ貫通する透孔4b(図12参照)と、搬送ベルト4の搬送側走行経路の下側に設けられて搬送ベルト4の下面に開口した負圧室7と、この負圧室7内のエアを吸引する吸引装置とで構成される。吸引装置は、外部カバー40の外に設置したブロア41等からなる。負圧室7とブロア41との間には、エア中の粉塵を除去するフィルタ42が設けられている。   The belt conveyor 1 is provided with air suction means 6 for attracting the workpiece W to the transport surface 4 a of the transport belt 4.

Countlessly mounted side by side, the outer shape constitutes a roll-shaped brush. The deburring member 22 is fitted to the outer periphery of the spindle 21 by the core tube 22a, and is fixed to the spindle 21 at both ends. The spindle 21 and the deburring member 22 constitute a roll-shaped rotating deburring body 23 that rotates integrally.

バリ取り部材22は、上記ロール状ブラシの他に、セラミックスのロールであっても良い。なお、バリ取り部材22とスピンドル21とは、必ずしも別体である必要はなく、一体の回転バリ取り体23として構成しても良い。   The deburring member 22 may be a ceramic roll in addition to the roll brush. Note that the deburring member 22 and the spindle 21 are not necessarily separate, and may be configured as an integral rotating deburring body 23.

図3において、上記第1および第2のバリ取りヘッド11,12は、バリ取りヘッド旋回駆動機構26により互いに同期して旋回させられる。また、各バリ取りヘッド11,12のスピンドル21は、各スピンドル自動駆動機構27,28により回転させられる。   In FIG. 3, the first and second deburring heads 11 and 12 are swung in synchronization with each other by a deburring head swivel driving mechanism 26. Further, the spindle 21 of each deburring head 11, 12 is rotated by each spindle automatic drive mechanism 27, 28.

第1および第2のバリ取りヘッド11,12は、これらバリ取りヘッド11,12の旋回によるバリ取り部材22の旋回領域R1,R2が互いに重なるオーバーラップ領域R12(図3に斜線を施した部分)が生じるように配置される。このオーバーラップ領域R12は、第1および第2のバリ取りヘッド11,12を、互いに旋回方向を逆方向として同期旋回させた場合に、互いの干渉は回避可能な範囲とされる。   The first and second deburring heads 11 and 12 are overlap regions R12 (parts hatched in FIG. 3) in which the swivel regions R1 and R2 of the deburring member 22 by the swiveling of the deburring heads 11 and 12 overlap each other. ) Is generated. The overlap region R12 is within a range in which mutual interference can be avoided when the first and second deburring heads 11 and 12 are synchronously swiveled with the swiveling directions being opposite to each other.

バリ取りヘッド旋回駆動機構26は、第1および第2のバリ取りヘッド11,12をオーバーラップ領域R12で互いに干渉させずに、これらバリ取りヘッド11,12を互いに旋回方向を逆回転として同期旋回させる機構である。このバリ取りヘッド旋回駆動機構26は、図10(A),(B)に各動作状態を示すように、いずれか一方のバリ取りヘッド11,12のスピンドル21が、その軸方向が搬送方向Xである前後方向を向いて前記オーバーラップ領域R12に位置するとき、他方のバリ取りヘッド11,12のスピンドル21は、その軸方向が左右方向Yを向いてオーバーラップ領域R12から外れるように位置させる。   The deburring head turning drive mechanism 26 synchronizes and turns the deburring heads 11 and 12 with the turning directions opposite to each other without causing the first and second deburring heads 11 and 12 to interfere with each other in the overlap region R12. It is a mechanism to make. As shown in FIGS. 10A and 10B, the deburring head turning drive mechanism 26 is configured such that the spindle 21 of one of the deburring heads 11 and 12 has an axial direction in the transport direction X. The spindle 21 of the other deburring heads 11 and 12 is positioned so that the axial direction of the other deburring heads 11 and 12 deviates from the overlap region R12 when facing the front-rear direction. .

図6、図7と共に、バリ取りヘッド旋回駆動機構26の具体的構成例を説明する。図6のように、第1および第2のバリ取りヘッド11,12は、それぞれの中心回転部材25が、ヘッド搭載台9の下面に回転支持部材29を介して上記旋回中心O1,O2回りに回転自在支持されている。バリ取りヘッド旋回駆動機構26は、旋回駆動用モータ30と、この旋回駆動用モータ30の回転を2系列に分岐して、各バリ取りヘッド11,12の中心回転部材25に同期して伝達する同期伝達機構31とで構成される。この同期伝達機構31は、各バリ取りヘッド11,12の中心回転部材25にその旋回中心O1,O2と同心に設けられた従動ギヤ32と、これら2枚の従動ギヤ32の間に配置され両従動ギヤ32にそれぞれ噛み合う2枚の中間ギヤ33と、片方の中間ギヤ33に噛み合う駆動ギヤ34とでなるギヤ列により構成される。駆動ギヤ34は、旋回駆動用モータ30の出力軸30aに直接に、または減速機(図示せず)を介して接続されている。上記2枚の中間ギヤ33は、それぞれヘッド搭載台9の下面に支軸35を介して回転自在に支持され、かつ互いに噛み合っている。このように、両バリ取りヘッド11,12の従動ギヤ32が、2枚の中間ギヤ33,33を介して互いに噛み合い状態にあるため、両バリ取りヘッド11,12は、互いの回転方向A,Bを逆方向として同期旋回する。   A specific configuration example of the deburring head turning drive mechanism 26 will be described with reference to FIGS. As shown in FIG. 6, each of the first and second deburring heads 11 and 12 has a center rotation member 25 around the pivot centers O 1 and O 2 via a rotation support member 29 on the lower surface of the head mounting base 9. It is supported rotatably. The deburring head turning drive mechanism 26 divides the rotation of the turning drive motor 30 and the turning drive motor 30 into two lines and transmits them in synchronization with the central rotating member 25 of each of the deburring heads 11 and 12. It is comprised with the synchronous transmission mechanism 31. FIG. The synchronous transmission mechanism 31 is disposed between the two driven gears 32 and the driven gear 32 provided concentrically with the turning centers O1 and O2 on the central rotating member 25 of the deburring heads 11 and 12. The gear train is composed of two intermediate gears 33 meshed with the driven gear 32 and a drive gear 34 meshed with one of the intermediate gears 33. The drive gear 34 is connected directly to the output shaft 30a of the turning drive motor 30 or via a speed reducer (not shown). The two intermediate gears 33 are rotatably supported on the lower surface of the head mounting base 9 via a support shaft 35 and mesh with each other. Thus, since the driven gears 32 of the deburring heads 11 and 12 are in mesh with each other via the two intermediate gears 33 and 33, the deburring heads 11 and 12 Rotate synchronously with B as the reverse direction.

なお、バリ取りヘッド旋回駆動機構26は、上記ように同期伝達機構31を用いる構成とする他に、バリ取りヘッド11,12に対して個別のモータを設け、両モータの回転を電気的に同期させる制御を行うものであっても良い。   The deburring head turning drive mechanism 26 is configured to use the synchronous transmission mechanism 31 as described above, and a separate motor is provided for the deburring heads 11 and 12, and the rotations of both motors are electrically synchronized. It is also possible to perform control.

図6において、各バリ取りヘッド11,12のスピンドル自転駆動機構27,28は、ヘッド搭載台9に設置されたスピンドル駆動モータ36と、このスピンドル駆動モータ36の出力軸に連結されて中心回転部材25の旋回中心O1,O2で回転自在な駆動軸37と、この駆動軸37の回転を各スピンドル21に分岐して伝達する分岐伝達機構38とで構成される。駆動軸37は、中空とされた中心回転部材25内に軸受(図示せず)を介して回転自在に支持されている。分岐伝達機構38は、内部構成の図示は省略するが、例えば駆動軸37に設けられた駆動側傘歯車と、各スピンドル21に設けられて駆動側傘歯車に噛み合う従動側傘歯車等で構成される。   In FIG. 6, the spindle rotation driving mechanisms 27 and 28 of the deburring heads 11 and 12 are connected to a spindle driving motor 36 installed on the head mounting base 9 and an output shaft of the spindle driving motor 36 to be a central rotating member. The drive shaft 37 is rotatable at 25 turning centers O1 and O2, and a branch transmission mechanism 38 that branches and transmits the rotation of the drive shaft 37 to each spindle 21. The drive shaft 37 is rotatably supported in a hollow central rotating member 25 via a bearing (not shown). The branch transmission mechanism 38 is configured by, for example, a drive side bevel gear provided on the drive shaft 37 and a driven bevel gear provided on each spindle 21 and meshing with the drive side bevel gear. The

第1のバリ取りヘッド11のスピンドル自転駆動機構27と、第2のバリ取りヘッド112のスピンドル自転駆動機構28とは、互いに異なる回転速度でスピンドル21を駆動させる。この場合に、スピンドル21の回転速度を速くする方のバリ取りヘッドは、第1、第2のいずれのバリ取りヘッド11,12であっても良い。また、両バリ取りヘッド11,12は、必ずしもスピンドル21の回転速度を異ならせる必要はなく、同じ回転速度としても良い。   The spindle rotation driving mechanism 27 of the first deburring head 11 and the spindle rotation driving mechanism 28 of the second deburring head 112 drive the spindle 21 at different rotational speeds. In this case, the deburring head for increasing the rotational speed of the spindle 21 may be either the first or second deburring head 11 or 12. Further, the deburring heads 11 and 12 are not necessarily required to have different rotation speeds of the spindle 21 and may have the same rotation speed.

図1および図2において、前記ブロア41の排気は、ダクト43を通って外部カバー40内の空間に送られて、バリ取り処理時に発生する粉塵を吹き飛ばすのに利用される。また、外部カバー40に設けたダクト接続口44に集塵ダクト(図示せず)が接続され、外部カバー40内の空間の粉塵が前記集塵ダクトを通って集塵装置(図示せず)へ送られる。   In FIG. 1 and FIG. 2, the exhaust of the blower 41 is sent to the space in the external cover 40 through the duct 43 and used to blow off dust generated during the deburring process. Further, a dust collection duct (not shown) is connected to a duct connection port 44 provided in the external cover 40, and dust in the space in the external cover 40 passes through the dust collection duct to a dust collection device (not shown). Sent.

前記ダクト43には、途中から分岐させて排気吹付け手段45用のダクト46が接続されている。排気吹付け手段45は、ブロア41の排気の一部を搬送ベルト4の搬送面4aに吹き付けて、搬送面4aに付着した異物および透孔4bに溜まった異物を除去され易くするためのものである。   A duct 46 for the exhaust blowing means 45 is connected to the duct 43 so as to be branched from the middle. The exhaust blowing means 45 is for blowing a part of the exhaust of the blower 41 onto the conveying surface 4a of the conveying belt 4 so that the foreign matters adhering to the conveying surface 4a and the foreign matters accumulated in the through holes 4b can be easily removed. is there.

排気吹付け手段45は、図11に示すように、搬送ベルト4における戻り部分の下方に、ブロア41から前記ダクト46を介して排気が送り込まれるエア溜り47を設け、このエア溜り47の上部に設けた吹出し口48から搬送ベルト4の搬送面4aに排気を上向きに吹き付けるようになっている。搬送ベルト4における戻り部分は、搬送ベルト4の移動経路中のワークWの搬送を行わない部分のことであり、この例では、搬送ベルト4における一対のローラ3間の部分に排気を吹き付ける。搬送ベルト4におけるローラ3に掛っている部分に排気を吹き付けるようにしても良い。   As shown in FIG. 11, the exhaust blowing means 45 is provided with an air reservoir 47 through which exhaust is sent from the blower 41 through the duct 46 below the return portion of the conveyor belt 4, and above the air reservoir 47. Exhaust air is blown upward from the provided outlet 48 to the conveying surface 4 a of the conveying belt 4. The return portion of the transport belt 4 is a portion where the work W is not transported in the movement path of the transport belt 4. In this example, exhaust is blown to a portion of the transport belt 4 between the pair of rollers 3. Exhaust gas may be blown onto a portion of the conveyor belt 4 that is hung on the roller 3.

エア溜り47の上部に設けた吹出し口48は、図12のように、搬送ベルト4の幅方向に長いスリット状である。先に説明したように、搬送ベルト4の透孔4bは、搬送ベルトの移動方向および幅方向に対して散在状態で配置されているが、吹出し口48が上記のようなスリット状であると、すべての透孔4bに均等に排気を吹き込むことができる。   The air outlet 48 provided in the upper part of the air reservoir 47 is a slit shape long in the width direction of the conveyor belt 4 as shown in FIG. As described above, the through holes 4b of the conveying belt 4 are arranged in a scattered state with respect to the moving direction and the width direction of the conveying belt, but when the outlet 48 is slit-shaped as described above, Exhaust air can be evenly blown into all the through holes 4b.

また、上記吹出し口48よりも搬送ベルト移動方向の上流側の位置に、搬送ベルト4の搬送面4aに付着した異物を掻き取る掻き取り手段50が設けられている。この例の掻き取り手段50は、搬送ベルト4と同程度の幅で先端が鋭利に形成された板状のスクレーパであって、このスクレーパを搬送ベルト4の搬送面4aに押し当てて異物を掻き取る構成である。掻き取り手段50は他の構成であってもよい。例えば、ワイパーのように掻き取り用部材(図示せず)を搬送面4aに沿って移動させる構成としてもよく、あるいはブラシ状の掻き取り用部材(図示せず)を、先端が搬送面4aに接する状態で回転または直線運動させる構成としてもよい。   Further, a scraping means 50 is provided at a position upstream of the blowout port 48 in the transport belt moving direction to scrape foreign matter adhering to the transport surface 4a of the transport belt 4. The scraping means 50 in this example is a plate-shaped scraper having the same width as that of the conveyor belt 4 and having a sharp tip, and the scraper is pressed against the conveyor surface 4a of the conveyor belt 4 to scrape foreign matter. It is the composition which takes. The scraping means 50 may have other configurations. For example, a scraping member (not shown) such as a wiper may be configured to move along the transport surface 4a, or a brush-like scraping member (not shown) may have a tip on the transport surface 4a. It is good also as a structure rotated or linearly moved in the state which contact | connects.

この構成の動作を説明する。人手により、ベルトコンベア1の図1における左端に、板金加工品である板材のワークWが載せられる。ワークWは、エア吸引手段6により搬送ベルト4の搬送面4aに吸着された状態で、図1の右方向へ搬送される。この搬送中に、ワークWが第1および第2のバリ取りヘッド11,12の下方を通過し、これらバリ取りヘッド11,12によってワークWの上面に形成されているバリが取られる。ベルトコンベア1の右端で、バリが取られたワークWが、人手により取り上げられる。   The operation of this configuration will be described. A work W made of a sheet material, which is a sheet metal processed product, is placed on the left end of the belt conveyor 1 in FIG. The workpiece W is conveyed to the right in FIG. 1 while being attracted to the conveyance surface 4 a of the conveyance belt 4 by the air suction means 6. During this conveyance, the workpiece W passes below the first and second deburring heads 11 and 12, and the deburring formed on the upper surface of the workpiece W is removed by these deburring heads 11 and 12. At the right end of the belt conveyor 1, the work W from which burrs have been removed is picked up manually.

搬送ベルト4の戻り行程において、まず図13(A)のように、掻き取り手段50によって、搬送ベルト4の搬送面4aに付着している異物60が掻き取られる。次に、図13(B)のように、排気吹付け手段45の吹出し口48から搬送ベルト4の透孔4b内へブロア41の排気が吹き付けられて、透孔4bの凹み部4baに残っている異物60が風圧で飛ばされて除去される。掻き取り手段50による掻き取りや、排気吹付け手段45による排気の吹き付けで、搬送ベルト4の搬送面4aおよび透孔4b内の異物60が完全に除去されなくても、排気を吹き付けることで残った異物60が乾燥するため、搬送ベルト4から剥離しやすくなる。そのため、搬送面4aを下向きにして搬送ベルト4が移動中に、異物60が自重で落下する。   In the return stroke of the transport belt 4, first, as shown in FIG. 13A, the scraping means 50 scrapes off the foreign matter 60 adhering to the transport surface 4a of the transport belt 4. Next, as shown in FIG. 13B, the exhaust of the blower 41 is blown into the through hole 4b of the conveying belt 4 from the outlet 48 of the exhaust blowing means 45, and remains in the recess 4ba of the through hole 4b. The foreign object 60 is blown away by the wind pressure and removed. Even if the foreign matter 60 in the conveying surface 4a and the through hole 4b of the conveying belt 4 is not completely removed by scraping by the scraping means 50 or by blowing exhaust gas by the exhaust blowing means 45, it remains by blowing exhaust gas. Since the foreign matter 60 is dried, it is easily peeled off from the conveyor belt 4. Therefore, the foreign matter 60 falls by its own weight while the transport belt 4 is moving with the transport surface 4a facing downward.

この実施形態のように、排気吹付け手段45によりブロア41の排気を吹き付ける箇所よりも搬送ベルト移動方向の上流側に掻き取り手段50を設けると、搬送面4aに大量の異物60が付着している場合でも、排気を吹き付ける前に異物60の大半を除去しておくことができる。そのため、排気を吹き付ける効果が残された異物60の深層部まで行き渡り、異物を綺麗に除去することができる。場合によっては、掻き取り手段50が設けなくても良い。   As in this embodiment, when the scraping means 50 is provided on the upstream side in the transport belt moving direction from the location where the exhaust of the blower 41 is blown by the exhaust spray means 45, a large amount of foreign matter 60 adheres to the transport surface 4a. Even if it exists, most of the foreign material 60 can be removed before blowing exhaust. Therefore, it can reach the deep part of the foreign matter 60 where the effect of blowing exhaust gas remains, and the foreign matter can be removed cleanly. In some cases, the scraping means 50 may not be provided.
